I don’t think I’ve ever hugged my mum! 😂
I don’t hug my teen DD either.
It sometimes makes me feel like I’m in the wrong but then I have to remind myself that she’s not physically affectionate and forcing her to hug would be unfair to her.
I completely get where you’re coming from.
Its likely that she too is ND but just the opposite of you.
I used to work with an autistic girl who liked hugs and it was honestly relentless.
No amount of physical affection was ever enough!
I would just keep reinforcing boundaries and asking for a hug.
Its not good if she’s hugging you when you are cooking or carrying something hot.
If she can learn to ask for additional hugs then you can tell her that you can’t right now as you are cooking etc.
I’d have a routine of giving hugs at certain times eg before leaving the house and then try and get her to ask for additional ones.
You could also do things like snuggle on the sofa on a movie night.
I do think you should keep in mind that it’s likely she’s ND.
Does she have any pets?
